Text Book Back Exercises Questions with Answers, Solution : 5th Maths : Term 3 Unit 1 : Geometry : Exercise 1.1 (Perimeter of the rectangle and square)

**Exercise 1.1**

** **

**1. How much wire will
be needed to make a rectangle of length 6 cm and breadth 3 cm?**

Length of the rectangle = 6cm

Breadth of the rectangle = 3cm

Perimeter of rectangle = (2×1) + (2×b)

= (2×6) + (2×3)

= 12 + 6

= 18cm

**Answer: 18cm
of wire will be needed.**

** **

**2. If the length of a
rectangle is 14 m and its breadth is 10 m, what is its perimeter?**

Length of the rectangle = 14 m

Breadth of the rectangle = 10 m

Perimeter of rectangle = (2×1) + (2×b)

= (2×14) + (2×10)

= 28 + 20

= 48 m

**Answer: Perimeter
of rectangle = 48m.**

** **

**3. Each side of a
square is 7 m long. Find its perimeter.**

Side of a square = 7m

Perimeter of a square = 4a

= 4×7

= 28m

**Answer: Perimeter
of a square = 28m**

** **

**4. If we take 2 rounds
of a field, that is 340 m long and 160 m wide. Find the distance covered in kilometers?**

Length of the field = 340m

Breadth of the field = 160m

Perimeter = (2×1) + (2×b)

= (2 × 340) + (2 × 160)

= 680 + 320

Distance for 1 round = 1000m

Distance for 2 rounds = 1000×2 = 2000m

1Km = 1000m

Distance covered in kilometers = 2000 ÷ 1000 = 2 km

**Answer:
Distance covered in kilometers = 2Km**

** **

**5. Sanju completes 10
rounds around a square park every day. If one side of the park is 110 m, then
find the distance covered by sanju in a day in terms of kilometers and metres.**

Side of a square park 110cm

Distance covered = Perimeter

Perimeter = 4a

= 4 × 110 = 440m

Distance for one round = 440m

Distance for 10 round = 440 × 10 = 4400m

Distance for 10 round in kilometers = 4400÷1000 = 4km 400m

**Answer: Distance
covered in a day in terms of kilometers = 4 km 400m **

**Meters =
4400m**

** **

__Answer:__

__Exercise 1.1__

**1. 18 cm **

**2. 4.8 cm **

**3. 2.8 cm **

**4. 1 km **

**5. 4400 m**
